Don't know about hdparm and ATA100 channels, but I got ATA100 working
with my i815-based mobo - the ASUS CUSL2. I had looked at linux-ide.org
and the 2.4 backport for UDMA 100 but I had also been told that it would
just be easier to use one of the 2.4.0-test?? kernels.
I am currently using the 2.4.0-test11 kernel (will soon upgrade to
test12) and have my UDMA100 HD recognized by the kernel:
hda: 40020624 sectors (20491 MB) w/2048KiB Cache, CHS=2491/255/63, UDMA(100)
It was a lot easier to use 2.4.0-test11 instead of trying the patch on
linux-ide.org. My recommendation would be for you to use 2.4.0-test12 to
get ATA100 support working, since the i815-chipset is natively supported
in 2.4.

The Linux 2.4.0-test series has all that you need, and then some. Just
curious, but how well is onboard ATA100 supported under FreeBSD ? What
about the other BSDs ? I plan on installing FreeBSD on my current system
but need to confirm that FreeBSD supports onboard ATA100 controllers and
ATA100 HDs.

Don't know about ReiserFS with Debian. Search through the debian-user
archives or post again about that if you haven't received an answer
about that.
If you decide to go with 2.4.0-test12, you will need to compile in the
following options to get ATA100 support working:
CONFIG_IDE=y
CONFIG_BLK_DEV_IDE=y
CONFIG_BLK_DEV_IDEDISK=y
CONFIG_BLK_DEV_IDEPCI=y
CONFIG_IDEPCI_SHARE_IRQ=y
CONFIG_BLK_DEV_IDEDMA_PCI=y
CONFIG_IDEDMA_PCI_AUTO=y
CONFIG_BLK_DEV_IDEDMA=y
CONFIG_BLK_DEV_PIIX=y
CONFIG_PIIX_TUNING=y
CONFIG_IDEDMA_AUTO=y
CONFIG_BLK_DEV_IDE_MODES=y
Write back if you run into problems.
HTH,
